The Solar Desalinations Prize is a four-round completion among developers of innovative technologies that will be used in the future for less expensive and more flexible desalination system.
Removing salt from water takes a lot of energy! Many of the largest untapped water resources in the US and around the world cannot be cost-effectively used because of high concentrations of dissolved salts.
Water treatment processes, like reverse osmosis, are efficient when salt concentrations are low, but can’t treat high-salt waters like those that are produced from oil and gas wells, concentrated brines, and some industrial and agricultural wastewaters.
Novel thermal desalination technologies can purify water with very high salt content without dramatically increasing the amount of energy required. By using solar thermal as the energy source, desalination technologies could be used in a variety of important environments, especially in arid areas with high sun exposure, where water purification is especially important.
Note that the Semifinalists will be announced April 12, 2021. I will post a link to this announcement as a comment to this paper as soon as I identify it.
